EB 80 BOXI Valve Island

4-POSITION VALVE ISLAND

The BOXI EB 80 is a 4-position electro-pneumatic manifold base for EB80 valves, available in 2 versions, with 4 or 8 controls for solenoid pilots. Up to 4 valves with one solenoid pilot can be installed on the manifold base with 4 controls, and up to 4 valves with one or two solenoid pilots can be installed on the manifold base with 8 controls.

INSTALLATION AND WIRING CONNECTION

CONNECTING UP THE MULTI-POLE ELECTRICAL CONNECTION
The solenoid valves of the island are powered and controlled via a D-Sub 9-pin connector with up to 8 solenoid pilots.
Only PNP pin configuration is allowed. There is no need for an auxiliary power supply, and control electronics can be actuated by any of the solenoid pilot commands. The power supply voltage can range from 12 to 24 VDC. Each control system output must supply the amount of power required to actuate the solenoid pilot.
The control system output current must be at least 500 mA.

WARNING!
Power off the system before plugging or unplugging the connector (risk of functional damage).
Use fully assembled valve units only.
Only use power packs complying with IEC 742/EN60742/VDE0551 with at least 4kV insulation resistance (PELV).
Earth the module using the connection identified with PE (see grounding connection).
Failure to earth the system properly may cause malfunctions and serious damage in the event of electrostatic discharge.
SUPPLY VOLTAGE
The system is designed to operate with wide power ratings, ranging from 12VDC -10% to 24VDC +30%, i.e. with a minimum voltage rating of 10.8VDC and a maximum of 31.2VDC.
WARNING!
Voltage greater than 32VDC will damage the system irreparably.
INPUT CURRENT
Solenoid valves are controlled via an electronic board equipped with a microprocessor.
In order to ensure safe operation of the valve and reduce energy consumption, a “speed-up” control is provided, i.e. 3W is supplied to solenoid pilot for 15 milliseconds and then power is gradually reduced to 0.25W.
The microprocessor regulates, via a PWM control, the current in the coil by compensating for any voltage variation.

PROTECTIONS AND DIAGNOSTICS

The island is protected against overload and polarity inversion.
In the presence of a short-circuit, the output command causes an irrevocable damage to the electronic board.
The overload or the command of a discontinued or failed control of a solenoid pilot is indicated by the flashing of the
ERR red. The permanent alarms stay on as long as a command remains active.
If the supply voltage is out of range, the fault is indicated by the steady activation of the ERR red LED light.
The valves continue to be operated, but correct operation is not guaranteed.

TYPE OF DATA IN THE BASES

= only one electrical control for each position. Can only be used with valves with one solenoid pilot, types V, J, G and R. If you use a N dummy or Y bypass valve, it is occupied an electric position.
= 2 electrical controls for each position. It can be used for all types of valves. If you use a V, G, J or R type valves (with only one solenoid pilot), N dummy or Y bypass valve, both electrical positions get occupied.

FIXING OPTIONS

Fixing on a DIN bar: fixing on a DIN bar in the sequence indicated. Fixing by means of brackets: the 3 brackets are already included in each EB 80 BOXI pack. Push them firmly into the appropriate seats on the base up to the “click”. 

EB 80 BOXI IO-Link DIAGRAM EB 80 BOXI is an electro-pneumatic base with 6 – 8 – 12 fixed positions for EB 80 valves, available in 2 versions, with 1 or 2 controls for each valve position. On the 1-control base it is possible to install valves with one solenoid pilot, on the 2-control base it is possible to install valves with one or two solenoid pilots.

INSTALLATION AND WIRING CONNECTION

CONNECTING UP THE MULTI-POLE ELECTRICAL CONNECTION
The solenoid valves of the island are powered and controlled via a D-Sub 26-pin connector with up to 24 solenoid pilots. Only PNP pin configuration is allowed. An auxiliary power supply is needed, used both for the control electronics  and for the power supply of the solenoid valves. The power supply voltage can range from 12 to 24 VDC.

= only one electrical control for each position. Can only be used with valves with one solenoid pilot, types V, J, G and R. If you use a N dummy or Y bypass valve, it is occupied an electric position.
= 2 electrical controls for each position. It can be used for all types of valves. If you use a V, G, J or R type valves (with only one solenoid pilot), N dummy or Y bypass valve, both electrical positions get occupied.

FIXING OPTIONS

Fixing on a DIN bar: tighten the screw on the end plate.

Fixing by means of brackets: the 3 brackets are already included in each EB 80 BOXI island. On the pressure inlet side, push the two brackets 1 firmly into the appropriate seats on the base up to the “click”. Tighten the screw on the end plate to secure the third bracket 2.

ADDITIONAL PNEUMATIC SUPPLY

During the configuration of the BOXI island, it is possible to insert, in the final position, an additional dedicated pneumatic supply and exhaust module, in order to increase the inlet and exhaust air flow rate of the island.
The module cannot be inserted into already assembled islands.
It is recommended in cases where there is simultaneous operation of several solenoid valves, with a flow rate request exceeding 3000 Nl/min*, or when it becomes important to have a quick pressure relief from ports 3 and 5.
It can be requested with a silenced exhaust or with a conveyed exhaust with fittings for Ø 8 – Ø 10, Ø 12 or Ø 1/2” pipes.

• Indicative value, depending on the operating pressure, the supply hoses and the specific needs of the application.
